Structure of non-global logarithms with Cambridge/Aachen clustering

K. Khelifa-Kerfa

We determine the structure of both Abelian and non-Abelian non-global logarithms up to four loops for $e^{+} e^{-}$ processes in perturbative QCD, where final-state jets are defined usi…

Hemisphere mass up to four-loops with generalised $k_{t}$ algorithms

K. Khelifa-Kerfa, M. Benghanem

We compute the fixed-order distribution of the non-global hemisphere mass observable in $e^{+} e^{-}$ annihilation up to four loops for various sequential recombination jet algorithms.…

Jet-mass in V/H+jet up to four-loops with $k_{t}$ clustering

K. Khelifa-Kerfa, M. Benghanem

We extend the work of [1] to the case in which final-state jets, produced in association with a Higgs or vector boson, are defined using the $k_{t}$ algorithm. We thereby compute the…

Dijet mass up to four-loops with(out) $k_{t}$ clustering

K. Khelifa-Kerfa

We compute the invariant mass of dijets produced in $e^{+} e^{-}$ annihilation processes up to four loops in perturbation theory for both anti- $k_{t}$ and $k_{t}$ jet algorithms. The calcu…

Non-global logarithms up to four loops at finite-N $_{c}$ for V/H+jet processes at hadron colliders

K. Khelifa-Kerfa

We extend our previous work [1] on calculating non-global logarithms in $e^{+} e^{-}$ annihilation to Higgs/vector boson production in association with a single hard jet at hadron coll…
